IMPROVEMENT IN B RIDLE BITS.

Specification forming part of Letters Patent No. 168,857., dated October 19,1875 application filed May 24, 1815.

To all whom it may concern? Be it known that 1, JAMES THORNTON, of Wellsvillc,in the county of Allegany and State of New York, have invented certain Improvements in Bridle-Bits, of which the following is a specification i My invention relates to a bridle-bit in which the mouth-piece is provided with two arms pivoted in two frames or cheek-pieces, which are attached at their upper ends to the headstall, while their lowerends are connected with the reins, so that by pulling on the latter the bit is raised in the mouth of the horse, as-will be hereinafter more fully described. 7

In the accompanying drawing, Figure 1 is a perspective view of myimproved bridle-bit. Fig. 2 is a side elevation with the mouth piece in its lowest positionl Fig. 3 is a similar view with the mouth-piece raised. Fig. 4

is a section in lines as m, Fig. 3. Fig.5 represents my improved bridle-hit with a slightlymodified form of cheek-piece.

Like letters of reference refer to like parts in each of the figures. I a

A A represent twov metallic cheek-pieces,

prci'erahlyof circular form, to which the lower ends of the straps B B of the headstall are attached by means of loops or a. c is a bar or hridge,-forming a pivot-bearing, arranged diametrically in the frames A, so as to be in a vertical position, or nearly so, when the frames.

A are in their normal position and the reins loose. d is a loop formed at or near the lower end of the bar 0'; for the attachment of theshown in Fig. at. When the mouth-piece is loops formed with or near the upper loops a a,

for the'attac hment of a chin or curb strap, h, as clearly shown in Fig. 1.

- When the rims are loose the mouth-piece E,

by reason of its gravity, assumes its lowest position in the mouth of the horse, as repre sented in Fig. 2. In tightening or pulling on the reins the loops a, to which the headstall' is attached, form fixed points or fulc'rums, on

which the frames A are swung backward, the pull of the" reins being applied. to the arms 0 of the mouthpiece at the pivots f, by which they are connected to the bare and the pivots f, traveling backward and upward in a curve described from the head-stall fastening a as a center. This pull on the mouth-piece causes the same to he raised iuthe mouth of the horse with great force, as the bar 0 operates as a lever and increases the pull of the the longest dimension in line of thebar 0,

when the pivot-hole iii the arms e'm'ust he elongated, in order to enabiethe mouthpiece: to travel on the oval frame, as is clearly shown in Fig. 5. 7

What I claim as myinventionis- The combinatiomwith the hearin' piecest', secured at theirupper'endstothe adstal'lg' and having the reins attached to their lower ends, of the hit E and arms 0, pivotedto the hearingpiece 0, suhstantially'a's and for the purpose hereinbefore set forth. 7
